### COMPA-RATIO ANALYSIS | Reward Management Procedures

A compa-ratio (short for comparative ratio) measures the relationship in a graded pay structure between actual and policy rates of pay as a percentage.

The policy value used is the reference point in the grade structure which represents the target rate for a fully competent individual in any job in the grade. This reference point is aligned to market rates in accordance with the organization's market stance policy. The reference point may be at the mid-point in a symmetrical range (say 100 per cent in a 80-120 per cent range), or the top of the scale in an incremental pay structure. Reference points need not necessarily be placed at the midpoint; organizations are increasingly positioning them at other points in the range.

Compa-ratios provide a shorthand way of answering the question: 'how high, or low, is an organization paying its employees (individually, in groups or in total) relative to its policies on pay levels?' Compa-ratios are calculated as follows:
A compa-ratio of 100 per cent means that actual and policy pay are the same; less than 100 per cent means that pay is below the reference point and greater than 100 per cent means that pay exceeds the reference point.

### Types of Compa-ratios

There are three types of compa-ratios:
1. The individual compa-ratio, which describes the individual's position in the pay range against the pay policy reference point for the range and can be used to reposition an individual's pay in the range if it is too high or low.
2. The group compa-ratio, which quantifies the relationship between practice and policy for the whole organization or a defined population group (function, department, occupation or job family). It is a calculation of the sum of actual pay as a percentage of the sum of job reference point rates. This ratio has an important part to play in the overall pay management process. It can be used to establish how pay policy has been implemented overall and identify differences between parts of the organization which may indicate problems in the policy itself or in the way it has been implemented by managers. It can also be used to plan and control pay budgets.
3. The average compa-ratio, which is the sum of each individual's compa-ratio divided by the number of individuals. It is therefore not the same as a group compa-ratio which is based on the relationship between the sums of actual rates of pay and the sums of job reference points of pay. The average compa-ratio can therefore differ from the group compa-ratio according to the spread of individual compa-ratios at different job sizes. The group ratio is more frequently used.

### Interpretation of Compa-ratios

Compa-ratios establish differences between policy and practice. The reasons for such differences need to be established. They may be attributable to one or more of the following factors:
• differences in aggregate performance levels or performance ratings;
• differences in average job tenure - average tenure may be short when people leave the job through promotion, transfer or resignation before they have moved far through the range and this would result in a lower compa-ratio. Or a higher ratio may result if people tend to remain in the job for some time;
• the payment of higher rates within the range to people for market reasons, which might require recruits to start some way up the range;
• the existence of anomalies after implementing a new pay structure;
• the rate of growth of the organization - fast-growing organization might recruit more people towards the bottom of the range or, conversely, may be forced to recruit people at high points in the range because of market forces. In a more stable or stagnant organization, however, people may generally have progressed further up their ranges because of a lack of promotion opportunities.
Some differences may be entirely justified, others may need action such as accelerating or decelerating increases or exercising greater control over ratings and pay reviews.
